Connection

Assembly

• 1-channel isolated barrier

• 24 V DC supply (Power Rail)

• TC, RTD, potentiometer or voltage input

• Redundant TC input

• Current output 0/4 mA ... 20 mA

• 2 relay contact outputs• Configurable by PACTwareTM or ke ypad

• Line fault (LFD) and sensor burnout detection

• Up to SIL2 acc. to IEC 61508

Function

This isolated barrier is used for intrinsic safety applications. Itis designed for a wide range of measurement applications. Itconverts the signal of an RTD, thermocouple, potentiometer,or voltage source to a proportional output current. It alsoprovides a relay trip value.

A removable terminal block K-CJC-** is available forthermocouples when internal cold junction compensation isdesired.

The unit is easily programmed by the use of a keypad locatedon the front of the unit or with the PACTware™ configurationsoftware.

A unique collective error messaging feature is available whenused with the Power Rail system.

Power feed module KFD2-EB2

The power feed module is used to supply the devices with 24 V DC via the Power Rail. The fuse-protected power feed modulecan supply up to 100 individual devices depending on the power consumption of the devices. A galvanically isolated mechanicalcontact uses the Power Rail to transmit collective error messages.

Power Rail UPR-03

The Power Rail UPR-03 is a complete unit consisting of the electrical inset and an aluminium profile rail 35 mm x 15 mm. To makeelectrical contact, the devices are simply engaged.

Profile Rail K-DUCT with Power Rail

The profile rail K-DUCT is an aluminum profile rail with Power Rail insert and two integral cable ducts for system and field cables.Due to this assembly no additional cable guides are necessary.

Power Rail and Profile Rail must not be fed via the device terminals of the individual devices!

K-CJC-**

This removable terminal block with integrated temperature measurement sensor is needed for internal cold junctioncompensation for thermocouples. One K-CJC-** is needed for each channel.

Adapter K-ADP1

Programming adapter for parameterisation via the serial RS 232 interface of a PC/Notebook

For programming, please use the new version of adapter K-ADP1 (part no. 181953, connector length 14mm). When using theprevious version K-ADP1 (connector length 18 mm) the plug is exposed by approx. 3 mm. The function is not affected.

Redundant thermocouple

For higher availability it is possible to connect a secondredundant thermocouple (B) of the same type to the

temperature converter. The cold junction temperature is takenfrom the connected terminal block.

If the deviation of the both thermocouples (A and B) exceed theselected tolerance, an error will occur. If a lead breakage of onethermocouple (e. g. A) has been detected, an error messageoccurs and the value of the second thermocouple (B) will betaken for futher calculation.
